The director of Mondovino, Jonathan Nossiter, is releasing a new documentary about natural wine called "Natural Resistance."
From Wine-Searcher:

While “Natural Resistance” is about wine, it is not intended to be a sequel to “Mondovino,” according to Nossiter. However, it’s likely to ruffle a few feathers. Not only does it extol the virtues of so-called "natural wine" – a term that has no agreed definition – it attacks the country’s quality system, the denominazione di origine controllata (DOC), as well as conventional grape growing methods.
“Natural Resistance” is “the most joyful and optimistic film I have ever made," said Nossiter. But the introduction to the 86-minute documentary, published in the Berlin Film Festival brochure, will displease many Italian wine producers within the country’s DOC system: “What looks like a bucolic paradise, where intelligent people produce wine according to time-honored and organic methods, is actually revealed to be a battleground. The DOC association, which is supposed to look after the interests of independent vintners, promotes winemakers who produce vast amounts in a standardized quality; and the agricultural industry with its hygiene regulations excludes traditional methods of production.”
It adds: “The only thing saving the landscape from being totally destroyed is affluent foreigners using the old vineyards as summer holiday homes.”
